安装 FlashAttention 的时候遇到报错：
Failed to build flash-attn
ERROR: Could not build wheels for flash-attn, which is required to install pyproject.toml-based projects
可能是安装的版本与环境存在冲突吧，我的环境是：
- python 3.10
- cuda 11.8
- torch 2.2
去 releases 里找符合版本的，然后安装
pip install flash_attn-2.5.7+cu118torch2.2cxx11abiFALSE-cp310-cp310-linux_x86_64.whl --no-build-isolation
安装成功：
